I used to play as well. I got into it during the Burning Crusade expansion and (to my greatest WoW shame) rolled a Blood Elf.
However, I quickly grew out of that silliness and rolled myself a troll shaman. Then when the WotLK expansion came out, I remade him into a troll DEATH KNIGHT. I really liked the "Blood" aspect, which used vampirism to heal wounds, which really goes well with troll cannabilism lore.
But, I stopped playing WoW because my computer died and this one I have now can't run it. It's for the best, as I'm probably going to start school again soon and I can't handle that timesink.
Real shame too, because Cataclysm will have WEREWOLVES EFF YEAAAAH.
